Donor Body Mass Index as a Risk Factor for Delayed Onset of Graft Function

Abstract

Delayed graft function continues to pose a significant challenge to clinicians in the context of kidney transplantation. The objective of this retrospective, 5-year analysis is to identify the parameters of beating heart donors and those of recipients that affect the delayed development of graft function. The monitored group was composed of 152 beating heart donors and 179 recipients. Delayed graft function was identified in 32 (17%) patients. The predictor for development of delayed graft function was the body mass index of the donor (odds ratio: 1.1473; 95% confidence interval [CI]: 1.0017-1.3140; P = .0472), and the independent risk factors were donor body mass index 30 to 34.9 kg/m² (hazard ratio [HR]: 6.0215; 95% CI: 1.4188-25.556; P = .0149), donor body mass index ≥35 kg/m² (HR: 13.5484; 95% CI: 1.4575-125.938; P = .0220), and abuse of alcohol in the donor’s history (HR: 1.779; 95% CI: 1.0679-2.964; P = .0270).
